Guhring 9055120079400 Taper Length Drill Bit 5/16 in

Product Description

The GUHRING 9055120079400 is a solid carbide taper length drill bit designed for demanding material removal in high-performance machining applications. Built to DIN 6537 standards, this bit features a 140-degree point angle with a self-centering SU point geometry and a web-thinned, tapered web configuration that reduces thrust and improves chip evacuation. The 5/16 inch (0.3125 inches) diameter bit runs with right-hand cutting direction and spiral fluting, making it suitable for machinists and tooling technicians working in precision drilling operations where tool life and hole quality are critical.

This drill bit is rated for use across a broad range of materials including steel, stainless steel, cast iron, hardened materials, brass, nickel alloy, and titanium alloy. The through-coolant capability supports high-speed, deep-hole drilling in CNC machining centers and production environments where heat management is essential. With a 7xD flute-length-to-diameter ratio and a maximum drilling depth of 2.523 inches (64.09 mm), it handles taper length applications in both job shop and production settings. It is installed by machinists and tool-and-die technicians.

Key Features

• Solid carbide construction for extended tool life in hard and abrasive materials
• 140-degree SU point angle with self-centering geometry reduces walking and improves entry accuracy
• Through-coolant capability supports deep-hole drilling and heat management
• Web-thinned, tapered web reduces cutting thrust
• 7xD flute length ratio provides a maximum drilling depth of 2.523 inches
• DIN 6537 compliant construction for consistent dimensional standards

Compatibility

Rated for use in brass, cast iron, hardened materials, nickel alloy, stainless steel, steel, and titanium alloy. Designed for use in straight-shank tool holders on CNC machining centers and drill presses that accept a 0.3150 inch shank diameter.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Ensure the tool holder and spindle are fully powered down and locked out before changing tooling. Verify the holder bore accepts the 0.3150 inch shank diameter and that the collet or chuck is clean and undamaged before seating the bit. When through-coolant is used, confirm coolant lines are properly connected and pressure is set per machine specifications before initiating a cut.
